You can integrate pressure field and shear stress field over the body surface (CFX-POST). If the integration is in the parallel direction to the flow you got drag force. If the integration is in the normal direction, instead, you got lift force.

Hi,
A better way is to use the force_x/y/z functions as that calculates the total force on the surface. These can be called as a CEL expression as the simulation progresses or done in post-processing in CFX-Post. Glenn Horrocks |
